A unique object is headed toward our Solar System. The object called 2014 UN271 (data recording started in 2014) appeared in the Dark Energy Survey collaboration on June 19, 2021 and is gaining popularity thanks to its extreme oddity. Information about this object appeared in the Minor Planet Electronic Cirulars, which generally includes "information on unusual minor planets and routine data on comets."
The very distant future, about a billion years from now, scientists say the atmosphere of Earth will contain very little oxygen. That will make the planet uninhabitable for complex aerobic life. Today, our atmosphere is about 21 percent oxygen, and that oxygen-rich nature makes it ideal for large and complex organisms like people.
When I grew up, I was told that our planet's core was made of lava - and that I'd never be able to dig through the planet to get out the other side. I was misinformed. While it still seems that I cannot tunnel through the planet (with the tools I have in my garage), the inner core of our planet Earth is apparently solid. Researchers Associate Professor Hrvoje Tkalčić and PhD Scholar Than-Son Phạm of The Australian National University (ANU) published a paper on the subject this week.
People have predicted the end of the world since ancient days, and this past September 23 was no exception. The Internet was alight with a doomsday prediction that billed this past Saturday as a fateful day, one that would result in the fabled planet Nibiru colliding with Earth and killing everyone. Forums were filled with people reporting feeling 'vibes' about the event; psychics said it would happen. But, as expected, the day passed without event.
A 13-year journey ends this week as Cassini–Huygens crashes into the face of Saturn - and we get to see it all happen. At the end of this journey, NASA is celebrating with an E-Book called "The Saturn System : Through the Eyes of Cassini." This E-Book was made free this week, and from it we've got a few passages and big set of photos to share with you today. These are just a few of the 450,000 photos captured by Cassini on its journey from Earth to Saturn.
They were close enough to have kissed. Considering Juno and Jupiter are wife and husband in the Roman pantheon, that analogy is seemingly appropriate. But if the Juno spacecraft were indeed close enough to kiss, and crash into, Jupiter, it would be like kissing one big red pimple. Juno just completed its seventh close flyby of our solar system’s biggest member and it has brought back some close up pictures of the Great Red Spot, the greatest storm we’ll ever see.
Is Pluto a planet or not? Depending the age of whom you ask, and depending they keep up with the latest new, they might answer yes or now. Apparently, it also depends whether you’re asking an astronomer or a planetary scientists. At least that’s the sentiment that NASA scientists, led by New Horizon principal investigator Alan Stern, is giving off in proposing a redefinition of what a planet is, which would re-induct Pluto to the club once again. Curiously enough, it would also add 100 new planets to our solar system alone.
Our solar system family is getting larger with the discovery of a new dwarf planet found orbiting beyond Pluto. This new dwarf planet doesn't have a fancy name like the major planets of the solar system, it's called 2014 UZ224 and is about 330-miles across. This little dwarf planet is about 8.5 billion miles away from the sun. Interestingly the dwarf planet is smaller than Pluto's moon Charon, which is about 750 miles in diameter.
We'd expect most new discoveries about Jupiter to be coming from the Juno spacecraft, which entered orbit around the planet early last month, but today we're hearing about a fascinating new find that Juno had nothing to do with. Scientists at the Southwest Research Institute have discovered that the atmosphere around Jupiter's moon Io is in a constant state of flux, collapsing and rebuilding once every day.
If you thought that Pluto was the gatekeeper of the outer edge of our solar system, your knowledge might need a massive update. Aside from comets that routinely orbit, and sometimes get too close, to our sun, there are a whole host of space objects beyond the little minor planet. And one of them might even be a planet in its own right. That is the discovery announced by Scott Sheppard of the Carnegie Institute of Washington last November 10. Simply called V774104, it is considered to be the most distant object in the solar system currently known.
Discovering a new planet is something that many astronomers dream of and at the ripe age of 15-years-old, an English high school student named Tom Wagg has done just that. Wagg has discovered a gas-giant exoplanet that he first came across two years ago while he was doing a work-experience study at Keele University in England. Additional observations of the planet have now been made and the existence of the planet has been confirmed.
You know something — Jupiter is huge. Like, really big. Turns out, it might be a bully, too. Like something out of The Matrix, two scientists now believe Jupiter actually destroyed version 1.0 of our solar system. Giving in to the Sun’s pull, Jupiter is believed to have come in and just obliterated other planets in our earlier solar system. The scientists point to strange quirks within our solar system as reason for their belief Jupiter was a cue-ball for an earlier version of our planetary scheme, and it makes quite a bit of sense!
